ALBERT KRAU'IH, OF HAMILTON, OHIO.

PAPER-CUTTER.

Specification of Letters Patent.

Patented June 2, 1914.

Application filed February 20, 1911. SeriaI No. 609,743.

1 b all Qlf/tOIH it may concern Be it known that I, ALBERT KIotU'rI-I, a citizen of the United States, residing at Hamilton, in the county of Butler and State of Ohio, have invented certain new and useful Improvements in Paper-Cutters, of which the following is a specification.

My invention relates to means for severing a strip of paper into predetermined lengths and compiling the same one above the other.

One of the objects of my invention is to provide means for cutting a strip of paper into predetermined lengths from a continuous roll, fed between combined feeding and serving rolls, one roll journaled yieldingly relative to its companion roll and against which it engages, together with means for releasing such engagement.

Another object of my invention is to provide means for severing a strip of paper into predetermined lengths, with means for feeding the severed or partially severed length, relatively faster than the feed of the strip to insure separation of the length from the strip.

Another object of my invention is to provide a machine for severing a strip of paper into predetermined lengths, with means for compiling the lengths, one above the other within a suitable compartment, or otherwise.

Another objectof my invention is to provide a machine, whereby the record strip of an autographic register can be severed into predetermined lengths, separating the indi vidual. sales records and compiling the same consecutively and within or upon a container.

Another object of my invention is to provide a pair of paper feeding and cutter rolls positively rotated relatively to each other, with a toothed cutter fixed upon the periphery of one of said rolls, and a tension plate yieldingly mounted upon said roll adjacent to the cutter blade, and a, compression bar mounted upon the opposite companion roller, adapted to register with said. cutter blade in the rotation of the rolls, for producing a transverse line of perforations through the strip of paper for partially severing the strip.

The various other features of my invention are more fully set forth in the description of the accompanying drawings, formmg a part of this specification, in which Figure 1 is a side elevation of my strip cutting machine. Fig. 2 is a top plan view thereof. Fig. 3 is a side elevation of the machine opposite that of Fig. 1. Fig. a is a section on line a", :11, Fig. Fig. 5 is a section on line '21, 1), Fig. l, and enlarged, of

one of the feeding and cutting rolls. Fig.

6 is an enlarged central verticallsection of the second cutting roll. Fig. 7 is a detail section on line 2, Fig. 3.

This machine is primarily adapted for cutting a strip of paper into undetermined lei'igths, the strip representing the record strip of an autographic register, which is usually rewound from one roll into another, and contains the records of sales and. the like. Such record roll is inconvenient in making book entries or using the same as a reference, for the stone must always be unwound when reference is desired to a particular record and then again rewound for filing. \Vith my machine, these individual records are severed from the strip and sequentially compiled in their order of record on the strip in substantially book form. Thus, convenient access and ready reference can he had to each record.

It is obvious, that the principle of my invention can 1 i applied directly within an autcgraphic register, severing the record lengths after each recording operation or entry in the use of the autographic register, instead of an independent machine, as herewith illustrated, without departing from any of the features of my invention. Further. while I have shown the same operated manually by a hand crank, it is obvious, that. any motive power may be employed or the same operated when used in conjunction with an autographic register by the manipulating means of the register, and, therefore, the broad principles of my invention relate to means for severing a strip of paper into a series of predetermined lengths and compiling the same one above the other in the order of severance.

In the drawings, 1 represents the side frzunes of the in a chine; 2 a pair of yielding roll supports or carriers mounted upon the side frames 1, and between which the roll of paper 3 is mounted, the roll-supporting arms applying the proper tension to the roll requisite in feeding paper therefrom and common in autographic registers.

l represents a guide plate which is secured between the side frames and over which the strip of paper is fed, so as to diroot the paper between the combined feeding and severing rolls 5, 6.

5 represents the lower feeding and severing roll journaled in a. fixed bearing between the side frames, the axle 7 thereof projecting through the bearings of the side frames and upon one end of which a hand crank 8 is fixed. The upper roll 6 is provided with an axle 9, journaled in the slide-block l0, slidably mounted in a bearing bracket 11, formed on the side frames 1, see Figs. 1 and 3. The slide-blocks 10 in each of the brackets 11 are maintained under clownward tension by a spring 12 mounted in each of the brackets to maintain the peripheries of rolls 5 and 6 under frictional engagement with each other for feeding the strip bet-ween the rolls. The cutters are provided with coacting cutter or perforating mechanism hereinafter described, which is relieved of any pulling strains through the feed of the paper by reason of the combined results of the rolls in feeding and partially severing the strip of paper. This form of feed and mechanism for mounting a pair of coacting rolls is old and wellknown in the art and commonly employed in autographic registers.

13 represents a pinion fixed upon the axle 7 of the lower roll in mesh with a pinion 1 st, fixed upon the axle 9 of the upper roll, for positively rotating said rolls relatively to each other to insure a predetermined length of feed of the strip of paper. The upper roll 6 is provided with a toothed cutting blade 15, fixed within a slot formed in said roll, with the toothed edge projecting beyond the periphery of the roll.

' 16 represents an ejector plate yieldingly mounted in a transverse slot formed in the periphery of the roll 6, telescopically enga ing over the cutter blade 15, and yieldingfy mounted on the roll by means of the lugs 17, or pins, projecting from the plate 16, and into an orifice formed in the roll, and 18 represents a spring engaging against each of said pins for exerting upward pressure to the plate 16, to project the same beyond the periphery of the roll. This plate is held in position by means of the collars 19, telescoped upon each end of the roll, see Fig. 5. Thus, as the plate 16 engages the periphery of the lower roll, it will be moved inward and automatically thrown outward by the tension of the springs 18, after the rolls have rotated beyond such plate engagement, the 1 rolls is plates serving to eject or discharge the strip of paper from any engagement with the teeth of the cutter blade and thereby pre vent any clogging of the machine at this point. The lower roll 5 is provided with a coacting tension plate 20, yieldingly mounted in a transverse slot formed in the periphery of the lower roll, and adapted to register with the cutter blade in the revolution of the rolls, so as to prevent slippage of the paper, as the teeth are forced through the paper as they are projected into the slot in the lower roll, within which the tension plate 20 is mounted. Upon each end of the tension plate 20, lugs 22 are provided adapt ed in the rotation of the roll 5, to engage with the periphery of the upper roll, to recede said tension blade with the intermeshing of the cutter within said tension blade slot, so as to relieve the cutter of any strains incident to such tension blade movement, while at the same time, the tension or engagement with the cutter is sutficiently maintained to prevent slippage of the paper and insure the proper cutting action. The tension plate 20 also prevents the paper from becoming engaged. or adhering to the periphery of the roller, which, if permitted, would readily clog the machine. Therefore, as illustrated, both the upper and lower rolls are provided with means for preventing the paper adhering or engaging with the cutter blade or rolls and thereby insuring a proper feed. The cutter blade is preferably made of toothed form, so as to make a. line of perforations through the paper, not a complete severing cut, and afterward severing the strip by a drawing action. The life of such cutter is greatly extended and renders the operation of the machine at a higher rate of speed than it is possible to produce with a straight cutting edge or shear cut.

23 represents a guide plate mounted between the side frames 1, and between the cutting rolls 5 and 6, and pull rolls 21 and mounted within bearings formed in the side frames 1. The lower pull roll 2% is jour naled in fixed bearings, 'while the upper pull roll is journaled in yielding bearings, with the peripheries of said rolls coactively maintained under tension. The upper roll is mounted substantially as the upper cutting and feeding roll 6.

96, 27, and 28, represent a train of intermediate gears in driving connection with gear 13, and with gear 28 in mesh with a gear 29 fixed upon the axle or shaft of the lower roll 24. This gear is of smaller diameter than the gear 28, so as to increase the rotation of the rollers 21-, 25, so as to cause a pulling action upon the partially severed length of paper and separate the same therefrom. The paper as it passes between these fed at' a greater rate of speed than the feed between the cutting rolls, thereby necessarily parting the paper along the line of perforations made by the cutter blade 15.

30 represents a gear fixed to the axis of roll 24, in mesh with a gear 31, fixed to the axle of the upper roll 25, producing a relative positive rotation of said rolls to insure the proper length of feed for each revolution thereof.

32 represents a hinged guide plate, adapted to direct the paper between the rolls 2i and 25. Said hinged plate is preferably hinged at its ends toward the pull. rolls, adapted to be swung in an upward vertical position. to enable the paper to be grasped by the operator, to properly adjust, the same relatively to the cutting rolls to insure a severing of the lengths along a proper line. AS shown, the cutting action is had. on each revolution of the cutting rolls and their diameter governs the length of the out strip, but it is obvious, that a series of cutters may be provided, so as to produce a series of cutting actions upon each revolution of the rolls. To release the frictional engagement between the peripheries of the feeding and cutting rolls 5, 6, the following means are provided.

34% represents cam levers pivotally mounted. upon the axle of the upper roll. 6 prov ided with the cam surface 35, adapted to be swung upon the periphery of the lower roll 5, thereby raisingthe upper roll and permitting the paper to be freely inserted and adjusted between said rolls. so represents a rod connecting said levers and forming hand held means for manipulating the same. The cam surfaces of levers 34 are engaged upon the periphery of the lower roll 5 by swing ing the engaging portions of the levers in a direction reverse to the feed of the paper for releasing the peripheral engagement of the rolls 5 and 6, and therefore, when the rolls are rotated in a direction to feed the paper, the levers will be automatically released from roll engagement obviating the necessity of manual release or disturb the cred lengths together.

operation of the rollers.

In order to compile and bind the severed lengths, the following instrulnentalities are provided :-37, 38, represent guide rods to properly direct and support the paper until it is released from its feed by the pull rolls 24v and 39 represents a swinging arm preferably formed with a medial loop 40. This arm 39 fixed to the rock shaft all. 4E2 represents an arm fixed to the rock shaft l1, and 43 represents a rod pivo-tally connected to said arm 42 and guided in the bracket 4A, projecting from one of the side frames, the opposite end of said. rod engag ing with the cam 45, fixed to the main driving shaft T. 46 represents a coil spring encircling said rod 43, one end engaging one of the brackets as, its opposite end engaging a collar 47, fixed on the rod 43. This spring maintains the free end of the rod in contact with the periphery of the earn 45, whereby the red at) is reciprocated through the rotation of the "am 45, thereby swinging the arm 39 upon each rotation of the main. drivingshaft 7. T he arm in normal position is swung upward, permitting the paper to pass between it and the guide rods 37 and 38, and at the proper time swung downward to deposit the cut length on the receptacle or container l9, detachably mounted. between the side frames 1. This container may be in the form of a base plate provided with a vertically projected pin oopupon which the paper is forced by the loop d0, of the arm 39, thereby securing the cut lengths in a compiled condition. 7

The machine is destined to teed a web between severing mechanism 'to divide the same into individual lengths, and advance each length to hinder storage mechanism to sequentially compile and bind the same. The disclosure herein having Special reference to record sales webs taken from or issuing from an autographic register co1n prising a strip of pa per. noting a series of individual sales or the like entries, each made within a defined area in sequence of issuance recorded by manifolding processes in an entry upon an original Slip or sheet.- and the length of each severed record entry may be equal or coordinate with the relative length of the original sales slips issued from the autographic register.

T he lengths after being severed from the continuous strip are serially advanced to a position to be engaged by the swinging arm 39 and sequentially compiled upon the binder pin 30, projecting from the storage compartuicut or container 49. The storage binder mechanism may be of any conventional form other than the container and binder pin illustrated. ha ving the utility of a loose sheet binder for either temporarilv or pern'ianently securing the sheets or sev- It is obvious, that by changing the outline of the cam the reciprmsation of the rod l3 can be relatively governed for producing a proper time movement of the 211111 39. to sequentially compile the lengths relatively with the speed or number of cuts made upon each revolution of the cutting rolls 5 and (i.
